Do you think I need a bigger boiler (it's already a pretty big
one)?
Or would a faster pump help?

Are the pipes large enough? Is there too many elbows rather than
bends?

How do you expect the original poster to know the answer to that?

Erm, erm, it's his system.

Oh, so now you think that everyone that owns a central heating system is
capable of calculating the required pipe sizes.

I'm sure he can tell us how much 22mm or 15mm there is.
